Which statement is true about natural numbers?

Which statement is true about natural numbers?

• A. Natural numbers are 1,2,3,... (zero is not included)
• B. Natural numbers include zero
• C. Natural numbers include negative numbers
• D. Natural numbers include fractions

Answer: (C)

Natural numbers are the numbers we use for counting objects. In the typical view, counting starts at one and goes upward without end, and zero is not included (though some conventions do include zero). They do not include negative numbers or fractions. So the true description is that natural numbers are the counting numbers starting at one and excluding zero. The other ideas don’t fit because natural numbers do not include zero (in the standard view), negative numbers, or fractions.
